Abstract
A system for acquiring images in color and near-infrared, comprising: a matrix sensor, which comprises first, second, and third types of pixels sensitive to respective visible colors and a fourth type of panchromatic pixels sensitive in the near-infrared; and a signal processing circuit configured to reconstruct first and second sets of monochromatic images, a panchromatic image, a color image from the images of the first set and from the panchromatic image, and at least one image in the near-infrared from the images of the second set and from the panchromatic image. A visible-near-infrared bispectral camera comprises such an acquisition system and method implemented by means of such a camera.
